ADVERTISING DEVICE.

Specification of Letters Patent.

Patented Jan. 20, 1914.

Application filed August 6, 1912. Serial No. 713,685.

To all whom it may concern:

Be it known that I, HARRY J. KEATING, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Advertising Devices, ofwhich the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to advertising devices and has for its specificobject the provision of a movable sign or advertisement.

The device in the form herein shown contemplates preferably a characterillustration which may be periodically changed so as to occupy differentpositions, and which at the same time has provision for the display, oneafter another of a plurality of cards of'advertising matter.

The invention herein concerns itself particularly with the operatingmechanism to direct a structure of this character, and while the same isherein set forth in connec tion with a device as above outlined, myinvent-ion is not to be so limited as it may be used in sundry wayswithout departing from its spirit, and the invention is of courselikewise capable of various modifications as will be readily understoodby those skilled in the art. I will describe however specifically oneform which my in vention may take by referring to the ac companyingdrawing, in which Figure 1 is a front view of a device adapted to beoperated in accordance with my invention; Fig. 2 is a rear view thereofshowing the operating mechanism, and Fig. 3 is a detail view of theoperating mechanism.

Referring specifically to Fig. 1, I set forth an advertising devicewhich may take the form of a man 1 who has a movable arm 2, in thisinstance designed to oscillate, the arm as here shown carrying a safetyrazor. The-lower portion of the device has a preferably circularaperture 3 through which is displayed certain advertising matterperiodically changed after a number of oscillations of the arm 2.

Referring more particularly to Fig. 2. I show the arm 2 as beingfastened to a pivotally mounted strip 3, said strip being pivotallymounted at 4 to a bracket 5 permanently secured to an upright 6,to whichup right the illustration is likewise preferably attached. The bracket 5also carries a spring 7. The arrangement of the arm is such that it isoverweighted, thereby tending to occupy the position shown in Fig. 2. Aplunger 8 controlled by a solenoid 9 as will presently appearperiodically draws the left hand extremity of the strip 3 downwardly,.whereafter the energization of the solenoid 9 is discontinued and theoverweighted arm 2 returns toward the position shown in Fig. 2, strikingagainst the spring 7 and thereby being rotated again in acontra-clockwise direction, Fig. 2, to assist the action of the solenoid9. The core 8 is connected by means of a rod 10 with the strip 3. Thecore 8 likewise carries a circuit controlling arm 11 and a cam 12. Acontact 13 is mounted on the outside of the solenoid and is connected bymeans of a conductor 14 with one terminal 15 of the solenoid and theother terminal 16 of the solenoid is connected by means of a conductor17 preferably with a lamp 18, which lamp 18 is then connected by meansof a conductor 19 with a generator 20, the other terminal of saidgenerator or source of current supply being connected by means of aconductor 21 with a cont-act spring 22 insulatingly mounted on thesolenoid structure. This contact spring has a downwardly extending arm23 adapted periodically to be engaged by the roller 24 carried by thearm 11. The spring 22 normally engages the contact 13 when the device isin the position shown in Fig. 3, thereby closing circuit through thesolenoid to attract the core 8 until such time as the cam 12 entersbetween the spring 22 and its mounting plate 25 and pushes the saidspring away from the contact 13. At this time the roller 24 is lowerthan the lowermost extremity of the arm 23. As the circuit through thesolenoid is broken, the

.overweighted arm 2 tends to return to its normal position and therebywithdraws the core 8 from within the solenoid, the roller 24 at the sametime engaging the righthand side of the arm 23 to maintain the spring 22away from the contact 13 until this roller 24 has been carried upwardlyto a point higher than the top of the spring 22, at which time the strip3 has engaged the spring 7 and is normally rotated in the oppositedirection to assist the solenoid 9 whose circuit has been again closedby the release of the spring 22 from the roller 24- to again attract thecore and carry the arm 2 in a contra-clockwise direction (Fig.

A plug 26 is preferably provided so that the device may be attached toany lamp circuit, which lamp or power circuit is diagrammaticallyindicated by the generator 20 in Fig. 3. The rod 10 also carries abracket 27 which has a pawl 28 cooperating with a ratchet wheel. 29 tomove this ratchet wheel one step for every complete movement of the arm2. A holding pawl 30 maintains the ratcnet in operated position. Theratchet is fixedly secured to a cam 31 which moves an arm 32 toward theright once for every complete revolution of the ratchet wheel This armhas a pivoted pawl 33 adapted to engage a star wheel 34 to move it to anangle of ninety degrees for very actuation of the irm It will thus beseen that depending upon the number of teeth in the ratchet wheel .29the star wheel 84: is rotated at predetermined angular distance once inthe course of any predetermined number of actuations of the arm The starwheel connected with a disk 35 having a plurality of advertising signsthereon which are adapted, one after another to be displayed through theopening 3, the disk 85 showing in dotted lines at 36 the outline of suchadvertising matter.

From what has been described it will be seen that I have provided a verysimple n'iechanism to control the oscillatory movement of the arm 2 andat the same time to control the periodic change of advertising matter.The broad feature of my invention will be thus understood and What Itherefore claim as new and desire to secure by Letters Talent is:

Apparatus of the character described comprising a movable element, asolenoid having a core to periodically actuate said element, saidelement being overweighted to automatically return to its normalposition when released from the influence or said solenoid, and meanscontrolled by said core to control the circuit through said. solenoid,said last aforesaid means comprising a con tact spring a contact, a camcarried by said core to break the circuit between said spring and saidcontact when said core is in its limiting position, and means tocontinue the interruption of said circuit until the said core has beenmoved to its other limiting position.

In witness whereof l hereunto subscribe my name this 92nd day of July,A. l)., 1912.
